Thanks for clearing that up-- obviously i wasn't correct in my assumption. Sorry if i misled anyone.

However, if i were running 10psi and 3bps with a reactor, wouldn't that be the same as 30psi and 1bps with an atomic diffuser? Or does the difference in volume not correlate that closely?

Regardless, i do believe that the GLA atomic diffusers are definitely some of the best on the market. The mist that they put out is much finer than what other atomic diffuser brands can do. While perhaps my previous statement about it being more efficient than a reactor may or may not be correct, the GLA atomic diffusers are extremely efficient themselves.
